Purulent nasal discharge is a common sign in the common cold and acute sinusitis. It is also a key trigger for prescription of antibiotics.1,2 Arroll and colleagues report their systemic review and meta-analysis of studies of the use of antibiotics in acute purulent rhinitis. They searched Medline, EMBASE, and the Cochrane controlled trials register and included controlled trials that studied purulent rhinitis, nasopharyngitis, common cold, and sinusitis where the study groups received an antibiotic and the control groups received a placebo. Acute was defined as less than 10 days. They found 5 papers that examined purulent rhinitis and 2 that examined rhinitis, but did not specify whether it was clear or cloudy. Several different antibiotics were studied: demethylchlortetracycline (demeclocycline, Declomycin® and others), amoxicillin (Amoxil® and others), co-trimoxazole (trimethoprim/ sulfamethoxazole, Bactrim® and others), and cephalexin (Keflex® and others).
Pooling the data, there was a significant benefit from antibiotics with a relative risk of 1.21 (95% confidence interval, 1.09-1.34, number needed to treat 8). Looking at adverse effects (primarily vomiting, diarrhea, abdominal pain, and rash), the pooled relative risk was 1.46 (95% CI, 1.10-1.94). The number needed to harm was 7.
Commentary
Eight men walk into a physician's office with green-yellow gunk coming out of their noses. We could treat all of them and, statistically, one of them might get better. On the other hand, at least one might suffer from an adverse side effect. What's a prudent physician to do?
Last year, Arroll et al published a systemic review of antibiotics for the common cold and acute purulent rhinitis.3 In it they concluded that the evidence of benefit with use of antibiotics for upper respiratory tract infections is too weak to recommend it, but the evidence in acute rhinitis, purulent or clear, was stronger. Since antibiotics can cause significant adverse effects, they did not recommend their routine use. A Cochrane Review of chronic (ie, 10 days or greater) purulent nasal discharge in children4 concluded that when there was radiographic evidence of sinusitis, antibiotics provided modest short-term help. The number needed to treat was 8.
Back to our prudent physician. The first step should be a discussion with the patient about the probable efficacy and the probable harm associated with use of antibiotics. Watchful waiting is appropriate. If something must be done, consideration should be given to nasal hypertonic saline irrigation. It is effective in acute sinusitis5 and well tolerated.6
